ANTIRATTLE-GATCH.

Specification of Letters Patent.

Patented June 22, 1920.

Application filed. .Tune 14, 191.9. Serial No. 304,119.

To all whom t may concern:

Be it known that I, CARL JOHN HAGsTnoM, a citizen of the United States, and a resident of Glen Cove, in the county of Nassau and State of New York, have invented a new and Improved Antirattle-Gatch, of which the following is a full, clear, and exact description.

This invention relates to builders hardware andhas particular reference to catches lby the other part and serving always to causethe bolt to swing on its pivot while a spring acts upon the opposite end of the bolt from its point for Ythe purpose of holding the bolt either in its locking position or at any other desired position according to the coperative relationbetween the socket piece and the bolt.

More definitely stated, assuming that the bolt is carried bythe door, or its equivalent, when the door is opened the keeper will cause the bolt to swing on its pivot to the extent corresponding tothe space between the striking edge of the door and the socket piece while the spring acts to hold the bolt with its point in precisely the position occupied by it when it swings with the door away from the socket piece so that when the door isagain swung shut said point of the bolt will pass freely past the outer portion of the socket piece and strike against a lip projecting inward toward the door from the main portion of the socket piece so that the closing of the door will automatically cause .the bolt to swing into holding position.

This device is especially designed for use in connection with doors for cupboards, refrigerators, bookcases, or'the like.

lith the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the inven- Vdoor. The free end ofthe spring tion is not restricted to the eXact details of .construction disclosed or suggestion herein,

still for the purpose of illustrating a practical embodiment thereof reference is yhad to .the accompanying drawings, in which like reference characters designate the .same parts inthe several views, and in which- Figure v1 is an outside perspective View of the main portion of the catchcomprising a casing and bolt.

.'Fig. 2 is a perspective view of the socket piece.

Fig. 3 is a horizontal sectional detail showing the' action of the catch while the vdoor .fis swinging shut.

Fig. 4; is a similar view showing the action lwhile the door is swinging open.

Fig. 5 lis a view indicating -the operation ofthe catch holding the door shut; and

Fig. 6 is adetail perspective View correspending to Fig. 1 but showing a different form of casing.

l/Vhile I show the casing and bolt carried by the movable member or door and the socket piece fixed to the jamb or frame, it is to be understood that this arrangement of the parts may be reversed if desired.

As shown in Fig. l the casing'comprises two side pieces 10 connected by a cross bar 11 at their innerends and by a face plate 12 atltheir outer ends, said face plate having holes 1 for screws for securing the body of the casing in a mortise 13 in the striking edge of the door. The face plate 12 is countlrsunk preferably flush with said striking e ge.

The bolt 14 is inthe nature of a lever of the first class pivoted between the side pieces 10 on ka pivot 15, while the active end or point 16 of the bolt projects beyond the `Vstriking edge of the door into or through a notch 17 formed in the face plate 12. The inner end of the bolt is rounded at 18 con. centric with the pivot and is adapted to bear Iagainst a leaf spring 19 arranged between the side plates 10 and having one end thereof anchored by means of a screw 20 to the bar 11. The face of the bar 11 against which the end of the spring is anchored by the screw 20 is preferably beveled at 11 so that the tension of the spring may be increased or reduced by turning the screw tighter or looser, access being had to the screw through a hole 21 formed through tle 19 a jacent to the rounded end 18 of the bolt is adapted to bear flatly against a flat face 22 of the bolt when the door is shut whereby the tensionA or force of the spring tends to hold the bolt in the position shown in Fig. 5 or substantially parallel to the plane of the door. When, however, the bolt is swung around its pivot through an angle of at least about degrees said free end ofthe spring will bear against the rounded end 18 which ybeing concentric with the pivot will always hold the bolt at the angle at which it may be turned.

Figs. 3, 4 and 5 show the tendency of the doors to shrink away from the jambs rendering ordinary catches ineffective or useless. This catch, however, operates just Vthe same irrespective of the reasonable distance of the striking edge of the door from ya hole 25 in its center into which the point of the bolt is adapted to be projected when the door swings shut, said point striking against the projecting lip 26 bent laterally from the plane of the socket piece toward the door. Said socket piece may be countersunk or set iush into the jamb so as to 'prov-ide for the closing of a close tting door.

lFig 3l indicates the closing action of the door and the point of the bolt striking against the lip 26 which will cause the turning'of the bolt around its pivot l5 so as to cause the spring to Y bear against the flat face of the bolt as shown in Fig. 5. Obviously the door may be pulled open by pullingon a knob or the like, not shown, and

' this opening movement will be resisted only by the force of the spring19 acting against Ythe flat face of the bolt. This force may be overcome by a pull on the door and when the door is so pulled open the point portion of the bolt will wipe against the conf Ftact portion 23 and cause the turning of the bolt around its -pivot as shown in Fig.

4. The spring will not act t0 cause the turning of the bolt while the door isV open, the bolt remaining stationary in the position caused to be assumed by it when the door isopened. The spring acts only as closing.

-Y By tightening the screw 20 causing the `anchored end of the spring to hugl more 4tightly against the bar 10,l the force of the a snap upon-the bolt after the bolt is turned toward its position parallel to the door when as will be plainly" seen from Fig. 5 with the screw tightened the force of the spring lwill act to hold the point of the bolt more firmly against the part 23 of the socket piece. This socket piece may be secured in the door` jamb by any suitable fastening devices passed through the holes 24.

In Fig. 6 the casing 27 is shown as of cylindrical nature rather than rectangular as in Fig. 1, otherwise the structure and operation are the same as already described.

Iclaim: Y

l. The herein described anti-rattle catch for Vdoors or the like comprising a casing and socket piece connected ,to the relatively movable parts, a bolt pivoted in the casing and. having an end projecting beyond the same, 'a spring acting upon the inner end of the bolt, said end being rounded whereby the force of the spring thereagainst while the door is being opened ywill serve to hold the bolt in any one of many various positions according to the space between the 'door and the jamb, and means carried by the laterally therefrom,a easing, a bolt pivoted v between its ends within the casing, one end of the bolt projecting beyond the casing and adapted to strike against said lip for turning the bolt into said opening into holding position, and a spring bearing frictionally against the opposite end' of the bolt and serving to hold the bolt in any one of many intermediate positions according to the space between the striking edge of the door and the j amb, and to resiliently hold the bolt in its holding or locking position. j

3. In a door catch, the combination of a casing, a bolt pivoted between its endsin the casing and having one .end projecting beyond the same, said bolt having a rounded end and a flat surface leading therefrom toward its opposite end, a flat spring within the casing adapted to bear against said rounded end and flat surface, means to anchor the springA to the casing providing for the variation in tension thereof, and means cooperatingy with said casing and bolt to cause the bolt to automatically move into locking position when the door is being closed. f

4. In a door catch, the combination of a casing adapted to vbe mortised in the striking edge of the door, a socket piece adapted to be fixed to the door jamb, said socket piece having a lip projecting toward the door, a bolt pivoted Within the casing and left automatically by Contact with the socket having one end projecting Well beyond the piece While the door is being opened and casing for cooperation with the socket piece acting upon the bolt to hold it substantially 10 lip irrespective of the distance between the parallel to the door in locking position when 5 door and the jamb, and a spring acting fricthe door is closed.

tionally While the door is being opened to hold the bolt in any angle at which it may be CARL JOHN HAGSTROM.
